To all 'whom t may concern.'

Be it known that I, FREDERICK P. Woon, a subject of the Kingdom of Great Britain, residing inuDetroit, in the county of Wayne and State of Michigan, have invented a new and useful Improvement in Coffee-Containers, of which the following is a specification. l

This'inventionrelates to an improvement in paper receptaclesfor aromatic food products', and the invention consists in combin. withthe paper walls of the receptacle a llmng of parchmentizedpaper cemented to the inner surface of the paper receptacle by a fused cement. y l l In the accompanying drawing which forms. a part of thisspeciication, Figure 1 is a perspective view of an ordinary coffee carton containing this invention. Fig. 2 is a horizontal fragmentary section of the same taken on the line 2--2 of Fig. 1.

It has long been lmown that parchmentized paper is to some considerable degree impervious to the aromatic oils of roasted and i ground coffee and that it isa useful material with which to line paper packages l'intended to hold teas. And it is also known that an intercalated layer of fused cement, such for example as asphaltum, etc., willlprevent the access of moisture to the interior of a paper container. I havev found by a series of exj periments that 1f a receptacle or carton be madeof paper and covered on the inside with a fused cement, to which is made to adhere while still hot a lining of parchmentized paper or hydrolyzed liber that the wholly unexpected result is produced of a package not merely Vinaccessible to' moisture but wholly impervious to aromatic oils to such extent that the package will not' long continue to smell of its aromatic contents after they are poured out, which shows'that none of the aromatic oils are absorbed.

In the accompanying drawing Al representsan ordinary coffee carton, B is a lining sheet ofhydrolyzed ber or parchmentized paper and C is the intercalated layer vor coating of fused cement which-causes the paper B -to adhere at all points to the carton Wall A.

I claim:

A paper walled container the walls of which consist of an exterior layer of paper; an interior layer of hydrolyzed ber; and an intermediate layer of fused cement adhering to and uniting said exterior and. interior l layers; said fused cement and hydrolyzed ber cooperating to prevent the absorption ofaromatic oils and thereby to preserve the llavor and prevent the deterioration of the contents of said container. f
